Interesting ticker. Yahoo normally calculates "previous close" as before last trading day, but Yahoo only has trading data for today. What do you think the previous close should be?

[playinlab]

Previous close is wrong for majority of data.

For example:
adidas AG (ADS.DE)
On summary tab Previous Close is 148.30
fast_info.previous_close returns 145.28

Data on historical data are not the same as data on summary tab.

I just wanted to pull the previous closing info.

[ValueRaider]

OK I got solutions:

'SOKE.IS'

Fall back to accessing info. No other way to access it.

'ADS.DE'

That previous close is in post-market, and Yahoo wasn't returning in a interval="1d" prepost=True fetch (some exchanges they do). A interval="1h" prepost=True fetch returns correct close.

Can close? @ValueRaider

[ValueRaider]

Not yet, want confirmation is fixed.

A fix is available is PIP pre-release and dev branch.

[ValueRaider]

Ticker.info is fixed and fast_info deprecated in latest release
